supports HTTP compression (Content encoding). Compression can have a
major impact on the performance of HTTP transactions. The only way to
obtain higher performance is to reduce the number of bytes
transmitted.</P
><P
>Using content encoding to receive a server's response you can reduce the traffic by twice or more.</P
><P
>The <A
HREF="ftp://ftp.isi.edu/in-notes/rfc2616.txt"
TARGET="_top"
>HTTP 1.1 (RFC 2616) specification</A
>
contains four content encoding methods: <TT
CLASS="LITERAL"
>gzip, deflate, compress</TT
>, and <TT
CLASS="LITERAL"
>identity</TT
>.</P
><P
>When Content-encoding is enabled,
<SPAN
CLASS="APPLICATION"
>DataparkSearch</SPAN
>'s indexer sends to a server
<TT
CLASS="LITERAL"
>Accept-Encoding: gzip,deflate,compress</TT
> string in HTTP
headers. </P
><P
>If the server supports any of gzip, deflate or compress
encoding, it sends gziped, deflated or compressed response.</P
><P
>To compile <SPAN
CLASS="APPLICATION"
>DataparkSearch</SPAN
> with
HTTP Content encoding support, the <TT
CLASS="LITERAL"
>zlib</TT
> library is
required.</P
><P
>To enable HTTP Content encoding support, configure
<SPAN
CLASS="APPLICATION"

> with the following
option:</P
><P
>		<KBD
CLASS="USERINPUT"
>./configure --with-zlib</KBD
